ARP 200-8635 Engine Cylinder Head Bolt Set

ARP maintains their reputation for zero-defect fasteners by controlling every aspect of manufacturing in-house. The 200-8635 is a complete cylinder head bolt set engineered for high-performance engine builds where reliability under extreme cylinder pressure is critical. These head bolts are manufactured from proprietary ARP2000 aerospace-grade steel alloy, heat-treated to deliver 200,000 PSI tensile strength—significantly exceeding the capabilities of standard Grade 8 hardware.

Key Features:

• ARP2000 alloy steel construction rated at 200,000 PSI tensile strength
• Black oxide finish for corrosion resistance and optimal lubrication retention
• Precision rolled threads for superior strength and fatigue resistance
• Underhead radius design reduces stress concentrations
• Complete bolt set includes all fasteners needed for cylinder head installation
• Each fastener meets ARP's stringent quality control standards

ARP head bolts are the gold standard for engine builders who demand maximum clamping force and long-term reliability. The superior material properties and precision manufacturing ensure consistent torque values and eliminate the risk of head gasket failure due to fastener stretch or fatigue.
